"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: retry verity reads for not-uptodate Merkle folios\n\nbtrfs_read_merkle_tree_page() can find a folio in the mapping that is not\nuptodate. After taking the folio lock, the current code treats that state\nas a read error and returns -EIO.\n\nThat can make a previous transient read failure sticky. If the failed read\nleft a not-uptodate folio in the mapping, later callers find that folio and\nfail instead of retrying the read.\n\nKeep the existing page-cache insertion and locking order, but retry the\nMerkle item read when a not-uptodate folio is found in the mapping. Also\nunlock the folio when read_key_bytes() fails so that a later caller can\nlock it and retry the read."
